Osmo Decking Oils are premium grade decking oils that are designed to enhance, protect and maintain softwood and hardwood decking boards. Osmo Decking Oil can be over-coated with a single coat of Osmo Anti Slip Decking Oil 430 if required.

Also suitable for garden furniture, screens and other exterior wood including pressure impregnated Pine, Douglas Fir, Cedar, Oak or Bangkirai - also suitable for Teak, Eucalyptus and other dense exotic hardwoods as well as thermo treated wood.

*Please Note: Osmo Decking Oil 007 (Clear) does not offer any UV resistance so although the decking will be protected from moisture, cracking, splitting and warping, it will not prevent decked areas from turning grey or silver over time.

Decking Oil 007 is a dual purpose product and is sometimes supplied and labelled as 'Teak Oil 007', this is confirmed by the text on the back of the tin. Please be advised that 125ml sample tins are printed in German only.

Decking boards must be clean, dry and frost-free prior to applying Osmo Decking Oil.

  1. Old paints, varnishes and other coatings must be removed by sanding or stripping back to clean, bare wood
  2. Old applications of oil based treatments or stains need to be cleaned or lightly sanded
  3. If sanding, use a 120 to 150 grit sandpaper and remove all traces of sanding dust before oiling
  4. Hardwoods with an especially high content of oil, leave to weather for about 2 to 3 months (in winter up to 5 months) or wipe over with White Spirit to degrease the surface
  5. Hard wood with a high content of natural wood extractives needs to weather off (for at least 4 weeks) before the initial treatment or to be cleaned with Osmo Brush Cleaner and Thinner (8000) (degreaser)
  6. Resinous wood e.g. Larch or Douglas Fir needs to weather off for at least 6 weeks
  7. Pressure impregnated wood, Massaranduba, Bangkirai or Garapa need to weather off for at least 3 months
  8. Use Osmo Wood Reviver Gel (6609) to clean the wood surface and remove greying before applying a decking oil
  9. For additional protection against blue stain, rot and mildew, pre-treat with Osmo WR Base Coat (4001) or with Osmo Wood Protector (4006) (biocide-free)

How To Apply Decking Oil

Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer's instructions on the tin at all times.

The type and age of timber can have a dramatic impact on how much decking oil the wood needs. As an example, softwood decking that is old will likely require more oil than a relatively new hardwood decking that still retains a fair amount of natural oil.

To test how much oil your decking needs, apply one thin coat, allow to dry, then apply a droplet of oil in a corner. If the droplet of oil soaks into the wood then a further coat can be applied. Repeat this process until the droplet of oil sits as a bead on the surface of the wood and no longer soaks in to the timber. This is an indication that the timber has absorbed as much oil as possible and doesn't require any more.

Stir the contents of the tin thoroughly before and periodically during use.

  1. Use an application brush or decking applicator to apply the decking oil thinly and evenly, along the wood grain
  2. For a quick and easy application, we recommend using the Osmo Floor Brush which is perfect for decking and allows for the decking oil to be applied from a standing position when used with the Osmo Telescopic Handle
  3. When applying decking oil, If possible apply the first coat on all sides of the decking boards before installation
  4. Wipe off any excess decking oil and allow 10 to 12 hours drying time, with good ventilation, then apply the 2nd coat - also thinly
  5. If a less intensively coloured result is desired, apply one coat of coloured decking oil followed with a second coat of clear (007), or a coat of clear Osmo Anti Slip Decking Oil (430)

Regular Cleaning

To preserve the look and performance of the oiled finish for longer, it is recommended that decked areas are swept with a stiff broom on a regular basis. This is to remove loose leaves, dirt and other organic matter that can settle on the deck and in the grooves, which can degrade or damage the finish and decking timbers over time.

Deep Cleaning

For deeper cleaning, to remove scuff marks, stains, grease or other contaminants, we recommend the use of a dedicated decking cleaner.


If the decking finish starts to look worn or tired over time as a result from heavy foot traffic or weathering, simply apply a fresh coat of Osmo Decking Oil following the Preparation and Application instructions above.

Q. Is there a specific time on how long an oiled deck will last before it needs re-oiling?

A. Unfortunately not. The reason for this is that the elements such as wind, rain and sun all have a degrading effect on the amount of oil in the wood. For that reason, every deck will be different because of location, shelter, weather patterns and general wear and tear.

Q. Is Osmo Decking Oil UV resistant to protect the colour of the decking?

A. As a general rule, the darker and stronger the colour is, the more UV resistance it provides. This is due to the pigments suspended in the oil blocking more of the UV rays. The clear variation (007) does not provide any UV protection. Decking treated with the clear version of Osmo Decking Oil will therefore be susceptible to the natural grey / silvering of the timber over time.

Q. I ordered a tin of Osmo Clear Decking Oil and received a tin labelled 'Osmo Teak Oil 007' is this correct?

A. Indeed it is. Osmo sell their Teak Oil 007 as a dual purpose product as it is perfect for Teak and decking, especially dark exotic hardwood decking which tends to be made from very dense and naturally oily woods.

Very easy to apply using the Osmo floor brush,took about an hour using the whole 2 5 ltr by John Johnson

Used the decking oil before I applied a second coat of Osmo anti slip. Was well impressed how easy it went on using the floor brush,was unsure that I hadn't bought enough but the 2.5 ltr did the job as it is quite a large area and has really enhanced the wood grain. Only been down a week but very happy with result.
